PD CEN/TS 14578:2013CEN/TS 14578:2013 (E) 4 Introduction System Standards EN 1796 and EN 14364 specify the properties of a piping
20、 system and its components when made from glass-reinforced thermosetting plastics (GRP) based on unsaturated polyester resin (UP) intended to be used for pressure and non-pressure water or sewerage applications. A System Standard includes specifications for pipes, fittings and joints and makes refer
21、ence to supporting standards covering test methods, recommended practices for installation (this Technical Specification) and procedures for assessment of conformity. Matters such as design procedures, determination of long-term safety factors based on a semi-probabilistic approach, surge allowance
22、and allowable negative pressures for buried GRP pipe applications are covered in CEN/TS 14807 1. This supporting Technical Specification, which covers practices for installation, is intended to be used in conjunction with ISO/TS 10465-1 by, amongst others, end-users, authorities, design engineers, t
23、esting and certification institutes and manufacturers. In this Technical Specification, much of the guidance is expressed as requirements, e.g. by use of “shall” or by instructions in the imperative. It is strongly recommended that these be followed whenever applicable. Other guidance is presented f
24、or consideration as a matter of judgement in each case, e.g. by use of “should”. PD CEN/TS 14578:2013CEN/TS 14578:2013 (E) 5 1 Scope This Technical Specification (CEN/TS) specifies recommended practices for the underground installation of piping systems made of glass-reinforced thermosetting plastic
25、s based on unsaturated polyester resin (GRP-UP), intended to be used for pressure or non-pressure water or sewerage applications and complying with, as applicable, EN 14364 and/or EN 1796. It is applicable to GRP-UP piping systems of nominal sizes from DN 100 to DN 4000 which are intended to be used
26、 for the conveyance of liquids at temperatures up to 50 C and at pressures of 0,5 bar and greater. Design procedures, the determination of long-term safety factors based on a semi-probabilistic approach, surge allowance and allowable negative pressures for buried GRP pipe applications are addressed
27、in CEN/TS 14807 1. Piping systems conforming to EN 1796 or EN 14364 can also be used for above-ground applications provided the influence of the environment and the supports is considered in the design of the pipes and joints. It is recommended to refer to ISO/TR 10986 4 for guidelines for the insta
28、llation of above-ground flexible jointed pipes. NOTE It is the responsibility of the purchaser or specifier to make the appropriate selections from these aspects, taking into account their particular requirements and any relevant national regulations and installation practices or codes. 2 Normative

In addition, see also EN 1796:2013 and EN 14364:2013 for general terms and defini
33、tions relating to GRP pipes. PD CEN/TS 14578:2013CEN/TS 14578:2013 (E) 6 4 Procedures 4.1 General Pipes and fittings covered by EN 1796 or EN 14364 shall be installed in accordance with ISO/TS 10465-1 taking into account the following information and guidance. In conditions not covered thereby, the
34、engineer shall make his own recommendations. Attention is drawn to the limitations that may apply to negative pressure in service, in particular if the pipe zone backfill material is removed and to mechanical compaction requirements during installation. This is of particular concern for pipe stiffne
35、ss up to and including SN 5000 (see also ISO/TS 10465-1). 4.2 Special conditions for pipes having a nominal stiffness less than SN 1250 Pipes having a nominal stiffness less than SN 1250 are not intended for laying directly in the ground. When installed in the ground, they shall be encased in concre
36、te. 5 Specific information and recommendations 5.1 General In ISO/TS 10465-1 reference is made to ISO product standards ISO 10639 3 and ISO 10467 2. These ISO product standards are similar to EN 1796 and EN 14364 respectively. For any such reference, substitute the respective EN product standard. 5.
37、2 Special transportation requirements When following the guidance given in ISO/TS 10465-1 particular care shall be taken to avoid impact damage. Pipes and fittings shall be secured before transporting them to or around the site. 5.3 Maximum storage heights on site Guidelines for the number of layers
38、 in a storage stack are given in ISO/TS 10465-1. The manufacturer may also supply specific storage recommendations. 5.4 Maximum storage period in direct sunlight When materials such as ultraviolet inhibitors have been incorporated or other protective pipe constructions have been used, pipes and fitt
39、ings may be stored in direct sunlight for their design lives. Care should be taken to protect rubber-sealing profiles from prolonged exposure to sunlight. Consult the manufacturer for all storage guidelines and recommendations. 5.5 Climatic conditions requiring special storage Apart from high winds,
40、 there are no climatic conditions that require special storage conditions for products conforming to EN 1796 or EN 14364. 5.6 Limiting deflections In no case shall the vertical diameter increase by more than 1,5 % of the mean diameter due to installation procedures, e.g. the relative initial ovaliza
41、tion shall not exceed 1,5 %. This may be verified by measurements when the pipe zone backfilling operation is completed. The initial deflection should be measured and monitored to assist in achieving a satisfactory installation. PD CEN/TS 14578:2013CEN/TS 14578:2013 (E) 7 The property requirements f
42、or GRP-UP pipes made in accordance with EN 1796 and EN 14364 assume that maximum permissible initial deflection is 3 % and the maximum long term deflection is 6 %. If the recommendations for installation in ISO/TS 10465-1 are followed it is expected that the deflections achieved will be less than th
43、ese limiting values. If the maximum long term deflection is different than 6 % the requirements are adjusted proportionally as covered in EN 1796 and EN 14364. 5.7 Coefficient of linear expansion A typical range for the coefficient of linear expansion in the axial direction, , is 20 106/C to 50 106/
44、C. This property varies with the nature, orientation and quantity of reinforcement in any particular pipe. The manufacturer shall provide the relevant information when requested by the purchaser. 5.8 Longitudinal tensile modulus and strength These properties vary with the nature, orientation and qua
45、ntity of reinforcement in any particular pipe. The manufacturer shall provide this information when requested by the purchaser. 5.9 Appropriate jointing system Joints described in and conforming to EN 1796 or EN 14364, as applicable, should be used. 5.10 Cold bending GRP-UP pipes are not suitable fo
46、r cold bending. Changes in direction should be achieved either by using fittings conforming to EN 1796 or EN 14364 or by utilizing the flexibility of the joint. 5.11 Permitted rates of loss of water and/or pressure Guidelines for testing both pressure and non-pressure systems is given in ISO/TS 1046
47、5-1. In addition, attention shall also be given to the requirements given in EN 805 and EN 1610 as may be applicable.
